Parking on Hills You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People canbe injured, and both your vehicle and the trailer canbe damaged. But if you ever have to park your on a hill, here's rig how to do it: 1. Apply your regular brakes, but don't shift into PARK (P) yet. 2. Have someone place chocks under the trailer's wheels. 3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load. 4. Reapply the regular brakes. Then apply your parking brake, and shift to PARK (P). 5. Release the regular brakes. Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you don't shift down, you might have to use your brakes so much that they would get hot and no longer work well. On a long uphill grade, shift down and reduce your speed to around 45 mph (70 k m h ) to reduce the possibility of engine and transaxle overheating. 4-39
